Math 2 Subject Test Prep

I started using the Barron’s book (8th edition, not the most recent) a couple months ago and I’ve gone through the whole book but I didn’t feel like I learned that much because the explanations are so convoluted and overly complex… and I took a couple practice tests but scored like 640 on each. So 2 weeks ago I bought the most recent Princeton Review book and I went through all of it and I feel so much more prepared, I scored an 800 on the first PR practice test I took. And I took a Barron’s test and scored 760-780 so I obviously improved a lot compared to the earlier 640.

But after reading a few threads on here everyone is saying that PR is way too easy for math 2 and doesn’t prep you enough. I’m taking the test in one and a half weeks, on December 5th. What do you think I should do next? Just take the last practice test in PR and take the remaining two practice tests from barron’s? Or should I prep more from Barrons, if so what material?
